Power Train Components PT203SS Stainless Steel Bearing Insert

The Power Train Components PT203SS is a stainless steel bearing insert engineered for reliable rotational support in industrial, agricultural, and power transmission applications. The SS designation indicates full stainless steel construction, providing superior corrosion resistance in environments exposed to moisture, chemicals, washdowns, or other harsh conditions.

Key Features:

• Stainless steel construction for excellent corrosion and rust resistance
• PT203 bore size — standard 17mm (0.6693 in) inner diameter for universal fitment
• Precision-ground races for low friction, smooth rotation, and extended service life
• Set screw locking collar for secure shaft retention
• Fits standard UC203 / insert bearing housings (pillow block, flange, and similar mount styles)
• Suitable for food processing, agricultural equipment, marine, and general industrial power transmission use

The PT203SS is a drop-in equivalent to the industry-standard UC203 insert bearing in stainless steel, making it an ideal upgrade or replacement for applications where a standard carbon steel bearing would corrode prematurely. Power Train Components manufactures this insert to meet or exceed OEM dimensional tolerances for confident, maintenance-friendly installation.
